The lead: GoPro shares get a boost after upgrade

GoPro jumped up 4.55 percent, or $2.59, to $59.50 on Thursday as Cowen investment analysts upgraded the San Mateo action-camera company with an overweight rating and a target price of $76, noting that GoPro “is not only a market leader, but actively expanding the category it created, with a range of devices that should appeal to sports enthusiasts and families.”

Analyst Robert W. Stone wrote that GoPro can broaden its sales among 18- to 34-year-olds, a group “most likely to include action sports enthusiasts.” By 2019, Stone wrote that the install base in the U.S will reach 20.8 million, equating to 28 percent market penetration in the aforementioned age group. Looking wider, over 50 percent of GoPro”s second-quarter revenue came from international sales, and Stone believes it”ll only get better from here.

“We expect international sales to outgrow the U.S. over the forecast period, so we estimate 45 percent of a projected 46 million 2019 active users are in the U.S.,” Stone wrote.

Stone praised GoPro”s diverse range of action cameras and sees immense growth in sales, with families becoming a growing market for the company, with some even purchasing more than one.

“We model cumulative capture device shipments of about 64.1 million by 2019. Net of replacements, we estimate about 50.9 milion active units,” Stone wrote. “We estimate 1.1 units per user, which equates to an average of one user in 10 owning a second camera. However, we believe multiple unit usage may grow, especially for families.”

Long-term, GoPro should be able to attract more users through its new content licensing platform, and the rise of VR headgear and service, he said. The Motley Fool was similarly bullish on GoPro, writing that the company was one of the prime tech hardware stocks to watch, alongside Apple.

“Like Apple, GoPro has built a brand that carries significant cachet among its expanding consumer base,” Keith Noonan wrote. “Its products are virtually synonymous with action cameras, enabling the company to succeed with a premium pricing model and generate strong margins.”

Apple was down 0.08 percent, or 9 cents, to $115.15, as the Cupertino tech giant”s latest diversity report shows that 50 percent of its hires in 2015 have been women, Hispanics, African Americans or Native Americans. Apple says it”s hired more diverse workers in the past 12 months than it ever has, with 11,000 women hired, a 65 percent yearly increase. Hispanic employees increased by 2,700, and African Americans employees increased by 2,200 in the same time period. CEO Tim Cook said he recognizes there is still much work to be done, though.
